The savings are more long term, and marginal at that in my experience. There are reloading calculators out there to help figure out the exact $ per round.
It took me no time at all to have my ammo equal the best store bought stuff that I've tried, and now I wouldn't go back.

It has it's own satisfaction making excellent ammo, and seeing the groups, especially if you like experimenting and are mechanically inclined.
The specific tailoring to each particular rifle's tolerances can't be matched by the standardized factory specs.
